What it is
Strata is a small toy for making landscapes. You get a block of land and water. Drag on it to raise hills, dig valleys, smooth slopes or plant trees, and the layers of rock show down the sides as you go.
Or press Generate for a whole new island, give it a biome and a season, and share it with a link.
What you can do
- Sculpt. Raise, lower, smooth and carve the land, with a brush you can resize.
- Grow. Plant forests by hand, or let trees fill in where they'd grow.
- Set the scene. Eight biomes, from tropical atoll to arctic and canyon, and four seasons.
- Bring it to life. Clouds, rain or snow, birds, fish, deer and the odd whale, and a day that passes.
- Share it. Every island has its own link, and there's a tilt-shift photo mode.


How it's built
It's built with Three.js on WebGPU, so it needs a recent Chrome, Edge or Safari. There are no models or textures to download: the land, water, trees and creatures are all made in code as you play.
